Bangkok Metropolitan Administration Governor MR Sukhumbhand Paribatra said Monday that he would seek footage of security cameras from private firms and shops near Victory Monument.

Sukhumbhand said the footages from the private sector might help identify the man who lobbed two grenades at the Victory Monument on Sunday.

The governors said 16 security cameras of the BMA failed to record anything because protesters had covered them with bags. He said he would ask the People's Democratic Reform Committee to remove the bags.
